The article analyzed the special rules used for size setting on production list model of knitted sweater CAD, It puts forward the special ways from aspects including size change adjustable points, setting established point, size setting efficiency and deviation size. It points out that two size change adjustable points in the same direction must be assured when setting size. All points in either vertical or horizontal direction must be turn into established points. Several methods on how to transform the un-established points to established points by transmitting characteristic and non-repetitive characteristic of setting established points are illustrated. It presents that we can improve efficiency by using local left-right asymmetric production list method for local asymmetric styles products of knitted sweaters. The effects and control methods of deviation size in the curve parts of model are analyzed.

Image matting is a fundamental operator in image editing and has significant influence on video production. This paper explores sampling-based image matting technology, with the aim to improve the accuracy of matting result. The result of sampling-based image matting technology is determined by the selected samples. Every undetermined pixel needs both a foreground and background pixel to estimate whether the undetermined one is in the foreground region of the image. These foreground pixels and background pixels are sampled from known regions, which form sample pairs. High-quality sample pairs can improve the accuracy of matting results. Therefore, how to search for the best sample pairs for all undetermined pixels is a key optimization problem of sampling-based image matting technology, termed “sample optimization problem.” In this paper, in order to improve the efficiency of searching for high-quality sample pairs, we propose a cooperative coevolution differential evolution (DE) algorithm in solution to this optimization problem. Strong-correlate pixels are divided into a group to cooperatively search for the best sample pairs. In order to avoid premature convergence of DE algorithm, a scattered strategy is used to keep the diversity of population. Besides, a simple but effective evaluation function is proposed to distinguish the quality of various candidate solutions. The existing optimization method, original DE algorithm and a popular evolution algorithm are used for comparison. The experimental results demonstrate that the proposed cooperative coevolution DE algorithm can search for higher-quality sample pairs and improve the accuracy of sampling-based image matting. © 2016 Springer-Verlag Berlin Heidelberg

The size of sleeve seam shrinkage is relative to the style of clothing and fabric properties, and influences aesthetics directly. In this paper, the relationship between fabric properties and sleeve seam shrinkage was discussed in detail, and the relationship between the material thickness and the sleeve seam shrinkage was found by numerical method. At the same time, the distribution of the sleeve seam shrinkage, and the determination method of the sleeve and sleeve hole fitting position were discussed. The method can be applied to fabric properties research and the garment production , and also can be used as a theoretical basis of the detemination of sleeve seam shrinkage for sample designers.

The article analyzed the special ways used for making the model production process list of asymmetrical sweater directed against the situation that points of models are bilateral symmetry and closely related in software. It takes several typical styles for example including buddhist monk robe, cutaway sweater, facing on one side shoulder etc. to explain the ways. Thought and main procedure are illustrated that are revising the neckline, canceling symmetry and using dimensions sign point, left and right sides knit technology independent, armhole and neck position interchange, double whole measurement in width etc. which can be used for reference to illustrate the principle on how to make the model production list of asymmetrical knitted sweaters by which various styles products of knitted sweaters with fresh and distinctive style model can be acquired in cad.

The article takes the knitting technology of tuck sleeve lady's knitted sweater as an example to put forward the idea on how to make complex sweater production process list. Pattern is got by using garment pattern design theory and main place sizes are given by messuring key parts of the pattern, Production process list is lade down based on the sizes. Variation of the key part sizes including armhole height and sleeve width are analyzed and relation curves are made from which we got the size change rule that armhole height increases linearly, however sleeve width nonlinearly with the increase of stretch variables that can be taken as reference for this style sweater for determining key part sizes. By combining widely used theory of pattern design with the principle of knitting technology of knitted sweaters, various styles products of knitted sweaters with fresh and distinctive style can be acquired.

Sampling-based image matting is an important basic operator of image processing. The matting results are depended on the quality of sample selection. The sample selection produces a pair of samples for each pixel to detect whether the pixel is in the foreground of an image. Therefore, how to optimize the production is usually modeled as a large-scale optimization problem. In this study, particle swarm optimization is applied to solve the problem because its property of rapid convergence is positive to the real-time demand of image matting. We regard every two dimensions of a particle as a sample pair for a undetermined pixel. The encoding can make image matting more effective when there are relevant pixels in the image. The experimental result indicates that the proposed particle swarm optimization performs better than existing optimization method for image matting. © 2015 ACM.

Previous studies have indicated phase-related differences in conditioned acquisition and extinction. In recent years, many researchers used event-related potential (ERP) technology to assess the extent of the acquisition and extinction. Therefore, this study was aimed to assess the sex- and menstrual cycle-dependent effects on the conditioned acquisition and extinction using ERP technology. Thirty-two females at two phases (menses phase, FM, and luteal phase, FL) of their menstrual cycle and 16 males participated in the experiment. The experiment consisted of two stages: acquisition stage and extinction stage. In the acquisition stage, in the predictable context, a condition stimulus (CS) was always followed by the presentation of a negative picture or a neutral picture; but in the unpredictable context, a CS was paired with a negative picture or a neutral picture 20% of the time. In the extinction stage, only CS was presented. The results showed that at acquisition stage, significant larger P2 amplitudes were recorded in female subjects in FL and FM in comparison with those of males. The female subjects in FL may acquire the strongest CS-US conditional connection. At extinction stage, the female subjects in FL showed larger P2 amplitudes than males, but there were no significant differences in P2 amplitudes between the males and females in FM. The results suggest that the females in FL allocate more attention resources to the acquisition of a conditioned response and delayed extinction. In conclusion, we suggest that female menstrual cycle may modulate conditioned acquisition and extinction processes, and our ERP data may provide an explanation for the premenstrual dysphoric disorder.

This paper employs a simultaneous equation model based on the model of Huang and Labys(2003) to describle the interactions among a set of variables such as economic growth, foreign trade, FDI and environmental pollution. An empirical test is made by using Chinese regional panel data in 1993-2007. The results indicate that export-oriented economy is good for local environments on the whole, and Environment Kuznets Curve holds true in China while Pollution Haven Hypothesis does not. © 2011 Published by Elsevier Ltd.
